To all whom it may concem:

Beit known that I, RAY W. PRITCHARD, a

citizen of the United States, residing at 2725 Oak street, in the city of Baltimore and State of Maryland, have invented certain particularly when they become deflated or partly'deflated and hence lap laterally over the edges of the rim where the latter enga s the head of the tire shoe or casing, and w1th this object in view, the a construction and arrangement of parts of which a preferred embodiment is shown in the accompanying drawing, wherein:

Figure 1' is a sectional perspective view of-zthe device applied in the operative position to a whee Fig. 2 is a side view of the device.

Fig. 3 is a detail view of the joints between the extremities of the guard showing the same separated.

The guard consists essentially of a roll 10 formed of relatively thin or sheet metal extended inwardly and then turned laterally to form a hook shaped flange 11 to lie in contact with the inner surface of the flange 12 of the tire rim 13 which in practice receives the bead 14 of the tire shoe or casing 15. The roll is positioned upon the exterior invention consists in surface of the flange 12 and any tendency of the tire shoe or casing to fold over the flange is prevented and the shoe is caused.

to describe a relative broad curve which" minimizes the tendency to out or break due to the weight of the car, said roll being eflectlvely held against displacement by reason of the engagement of the casing bead 14 with the flange 11.

In practice the roll may be' provided with a core or filler 16 consisting of a-wire or rod of any preferred diameter and at the extremities of the guard the sheet metal casingand core or filler are cut as indicated in Fig. 3 to lie in Interlocking relation, so that further fastening means to insure retention of the tions is avoided.

hat is claimed is s a means to prevent rim-cuttin tlre, a flange to en age the inner sur e. the bead-securing integral with the therefrom over the the proper parts in their desired relaof -a ange of the a flange first flange; extending edge of the-head securingflange and being curled intoj a tube en-v gaglng the exterior of the securing flange whereby the tube and first flange clasp. the

bead securing flange, said means beingresilient and split with overlapping portions 'at the tube, and a means in the tube extending into the overlapping portions to reinforce them.

In testimony whereof I afiix in presence of two witnesses.

RAY W. PRITC HARD.
